Allonnia, a Boston-based bio-ingenuity company focused on improving mineral recovery while reducing environmental impact, has raised more than $20 million in a Series A extension round. The financing was led by Viking Global Investors, Bison Ventures, General Atlantic, BHP Ventures, and Pivotal Capital Partners, bringing the company’s total funding to more than $100 million.
The new capital arrives at a time when global demand for copper, nickel, lithium, and rare earth elements continues to accelerate, driven by electric vehicles, grid electrification, artificial intelligence, data center applications, and national security systems. At the same time, declining ore grades, which have fallen by as much as 50 percent over recent decades, are placing increased pressure on miners to extract greater value from existing operations while limiting environmental impact.
Allonnia is positioning its D-Solve platform as a solution to this challenge. The technology is designed to integrate directly into existing mineral processing flowsheets as a bolt-on process. It uses Allonnia Biosolution™, a selective, recyclable solution that dissolves and removes problematic gangue minerals, producing cleaner, higher-value concentrates. By improving recovery and throughput, the platform aims to reduce tailings volumes and lower chemical usage at mine sites.
According to the company, the Series A extension funding will support the commercial rollout of D-Solve™, including the deployment of its first mine-site pilot. This follows a five-day continuous demonstration conducted at SGS Lakefield in Ontario, where the technology achieved a 40 percent reduction in magnesium impurities and an 18 percent increase in nickel grade. Building on those results, Allonnia announced in August 2025 plans to deploy its first mobile D-Solve unit at Eagle Mine, the only active nickel mine in North America, with field operations beginning in December.
Investors backing the round view Allonnia’s approach as addressing a critical bottleneck in the global mineral supply chain, particularly as the energy transition places increasing demands on sustainable, scalable extraction technologies. The company is continuing to expand its selective separation portfolio across two primary markets. These include metals and mining, with applications such as impurity removal, concentrate upgrading, and rare-earth recovery, as well as emerging contaminants, where Allonnia offers solutions such as SAFF®, its PFAS treatment platform.
Allonnia is headquartered in Boston’s Seaport District and continues to focus on translating laboratory and pilot-scale successes into commercial deployments across active mine sites.
KEY QUOTES:
“The world cannot meet its critical mineral needs with traditional approaches alone. D-Solve provides a new path forward by improving concentrate quality, increasing production and reducing the burden of inputs and waste. This investment accelerates our ability to transition from successful demonstrations to real world impact across active mine sites.”
Nicole Richards, CEO, Allonnia
“Allonnia is developing differentiated biotechnologies to address critical challenges in mineral supply chains. We are pleased to deepen our partnership with Allonnia as the Company continues to translate its strong technical foundation into practical, scalable, and innovative solutions.”
Brett Zbar, Managing Director And Global Head Of Life Sciences, General Atlantic
“At Bison, we invest in companies that pair scientific ambition with a disciplined path to market. Allonnia exemplifies this approach through the development of the type of breakthrough technologies needed to strengthen critical mineral supply chains and reduce environmental impact. The team has a history of demonstrated speed, discipline, and a clear line of sight to commercial adoption building on their success with commercialization of PFAS separation and concentration solution.”
